Barren Island is a small volcanic island in the Andaman Sea, part of the Andaman Islands of India, and is the only historically active volcano in the region. The island has produced intermittent eruptions in recent decades and is geologically notable within the Andaman archipelago.
The island is uninhabited and visits are restricted because of volcanic risk and remoteness; nearby liveaboard and research vessels occasionally approach the island for observation. The island’s fresh lava flows and barren slopes contrast with the forested Andaman main islands.
Barren Island’s eruptions have been recorded in the 21st century and it is monitored by geological authorities in India. No permanent settlements are present and the island is primarily of interest to volcanologists and maritime observers.
The island lies in the southeastern Bay of Bengal, east of the main Andaman group, and is reached only by boat from larger islands and mainland ports with appropriate clearance.
- Volcanic status: It is the only confirmed active volcano in the Andaman Sea and the only historically active volcanic island of the Indian subcontinent.
- Access: Uninhabited and restricted for safety; boat access is controlled and generally limited to scientific or authorised visits.
